O world, thou choosest not the better part! <br />It is not wisdom to be only wise, <br />And on the inward vision close the eyes, <br />But it is wisdom to believe the heart. <br />Columbus found a world, and had no chart, <br />Save one that faith deciphered in the skies; <br />To trust the soul's invincible surmise <br />Was all his science and his only art. <br /> <br />Our knowledge is a torch of smoky pine <br />That lights the pathway but one step ahead <br />Across a void of mystery and dread. <br />Bid, then, the tender light of faith to shine <br />By which alone the mortal heart is led <br />Unto the thinking of the thought divine.<br /><br />George Santayana<br /><br />http://www.poemhunter.com/poem/sonnet-iii/
